June is unique among the calendar months, possessing not one, but three recognized birthstones: Alexandrite, Moonstone, and Pearl. This multiplicity isn’t the result of ancient tradition, but rather a response to evolving market demands and the discovery of new gemstones in the 18th through 20th centuries. While each stone holds individual beauty and symbolism, their collective designation reflects a desire to offer a range of options to suit different tastes and budgets. This article will delve into the history, geological origins, gemological properties, and cultural significance of each of these captivating June birthstones.
A History of Multiple Designations
The practice of associating specific gemstones with each month dates back to ancient times, though the stones themselves have varied across cultures. Initially, diamonds and sapphires were considered ancient birthstones, while garnets and lapis lazuli were among the traditional choices. However, as more gemstones were discovered, the National Association of Jewelers convened in 1912 to standardize a modern list, resulting in the inclusion of Alexandrite, Pearl, and Moonstone as the birthstones for June. The original need for multiple stones stemmed from the rarity and expense of certain gems, making them less accessible to the broader market. As demand for birthstone jewelry grew in the 20th century, pearls and alexandrite alone could not meet consumer needs, leading to the addition of moonstone as a more affordable alternative.
Alexandrite: The Color-Changing Gem
Alexandrite, a member of the chrysoberyl family, is perhaps the most remarkable of June’s birthstones due to its exceptional color-changing ability. This phenomenon, known as the Alexandrite effect, is caused by the stone’s absorption of different wavelengths of light under varying light sources. In daylight, Alexandrite typically appears bluish-green, while under incandescent light, it transforms into a purplish-red hue. This dramatic shift is attributed to the presence of chromium within the gem’s crystal structure.
The rarity of natural, fine Alexandrite contributes to its high value. It was first discovered in Russia in the 1830s in the Ural Mountains, and was named after Prince Alexander II of Russia. Today, Alexandrite is also found in Brazil, Sri Lanka, and East Africa, though these stones often exhibit less pronounced color change. Alexandrite is connected to the zodiac signs Gemini and Scorpio, believed to support clarity of thought and emotional balance for Geminis, and enhance intuition for Scorpios. In Hindu astrology, it is considered a substitute for emerald and is thought to bring good fortune and creativity.
Moonstone: The Ethereal Glow
Moonstone, a variety of feldspar, is characterized by its captivating shimmering iridescence, known as adularescence. This optical phenomenon is caused by the scattering of light between microscopic layers within the stone. Moonstones exhibit a range of colors, including white, blue-purple, and pinkish-brown, with the most prized specimens displaying a clear, billowy sheen.
Throughout history, moonstone has been associated with various myths and beliefs. Ancient Greeks believed moonstones were formed from solidified moonlight, while Romans associated the stone with the goddess Diana. In Chinese mythology, moonstones were thought to be the crystallized essence of moonlight. Moonstone is often linked to feminine energy, intuition, and emotional balance. Both natural and lab-grown moonstones are available, offering options for different budgets and preferences.
Pearl: A Gift from the Sea
Pearls are unique among gemstones as they are organic, formed within the soft tissue of living mollusks – typically oysters or mussels – in both freshwater and saltwater environments. The formation of a pearl begins when an irritant, such as a small bead or piece of shell, enters the mollusk. The mollusk then coats the irritant with multiple layers of calcium carbonate, the same mineral that comprises its shell, gradually building up the pearl over time.
The color of a pearl is influenced by the color of the host shell, resulting in a wide spectrum of hues, including white, cream, pink, silver, gold, and black. Pearls have been revered for centuries, with ancient peoples attributing mystical properties to them. In the Middle East, pearls were believed to be the hardened tears of joy shed by Aphrodite, the goddess of love. Chinese mythology associates pearls with dragons and wisdom. Cleopatra famously dissolved a pearl in vinegar to demonstrate her wealth and affection. Cultured pearls, where the pearl formation is initiated by humans, have become more accessible, making them a popular choice for jewelry.

Symbolism and Metaphysical Beliefs
Each of June’s birthstones carries its own unique symbolism and metaphysical associations. Alexandrite is often linked to good fortune, balance, and intuition. Moonstone is believed to enhance intuition, promote emotional balance, and foster feminine energy. Pearls symbolize purity, innocence, and wisdom, and are often associated with love and marriage. These symbolic meanings contribute to the enduring appeal of these gemstones and their significance as birthstones.
Care and Cleaning
Due to their varying hardness levels, each June birthstone requires specific care to maintain its beauty. Alexandrite, with its high hardness, is relatively durable and can be cleaned with warm, soapy water and a soft brush. Moonstone, being softer, is more susceptible to scratches and should be handled with care. It is best cleaned with a soft cloth and mild soap. Pearls are the most delicate of the three and require gentle cleaning with a soft cloth and lukewarm water. Avoid harsh chemicals, ultrasonic cleaners, and abrasive materials when cleaning any of these gemstones.
